good luck for tomorrow everyone! and remember, dont post comments after the exam until 4:30am on saturday morning, as it is an international paper, therefore some people wont have taken it until this time!

some help please. in simple harmonic motion with a vertical string, when does the situation stop being modelled as shm - when the string goes slack or at equilibrium position?

Slack i believe.... but itll go slack as soon as it passes the eqm point (on the way back up) then itll act under gravity :smile:

Don't discuss the exam until tomorrow or you'll get 10 warning points if they find you *looks around nervously*

Hasn't attracted too much attention - we're still on the first page lol - so I guess a mod hasn't seen it yet.

Thread closed until midnight.

As to why the thread was still open; I do have a life, and I was somewhat hoping that people doing the likes of M3 wouldn't be breaking the rules anyhow.

Haha, I probably failed it. I hate M3.

That velocity as a function of displacement was hard and I couldn't do the T=3mgcos whatever question.

Went pretty well, hoping for 75/75 but nothing is sure at this stage.
Overall the paper was quite simple except a tricky kinematics question which gave velocity as a function of displacement.
How was your exam?

well i messed up the 9 mark gravitation question and couldnt prove the centre of mass 1.42 cm thing, so i just hope they mark my paper generously, as the boundaries are always very high on m3
